Abstract

The basic principle of quadratic permutation polynomial (QPP) over finite field is firstly described. Then, it is applied to turbo codes interleavers. The searching metric satisfying the permutation on interleaver coefficients is presented to improve the performance of the corresponding turbo code. The performance comparison between QPP and other algebraic interleavers is also given. Finally, a detailed turbo coding scheme is designed for deep-space communication. The simulation results show that such a scheme satisfies the requirement and can be easily implemented.
